“…The most important feature of the promising reconfigurable supercomputer is the support of unique computing power by the extensive capabilities of data exchange configuration. It represents multiple communication channels between FPGAs within the CB, as well as between FPGAs of neighboring CBs [13].The structure of information links has been clarified at operating with the CB topology and designing technical solutions. Communication between FPGAs is provided via differential lines using multi-gigabit transceivers (MGT), integrated into the FPGA.…”

In the paper we consider a promising universal reconfigurable supercomputer, the computing nodes of which are reconfigurable computing device Arcturus. It was developed at the Supercomputers and Neurocomputers Research Center (Taganrog) and based on modern Xilinx FPGAs of UltraScale+ family of HBM-series. The purpose is to achieve the highest computational layout density, to ensure balanced power supply and cooling, as well as the implementation of powerful data exchange configuration. The supercomputer can have up to 1.5 thousand FPGAs of a single computing field. It has extensive information exchange capabilities between FPGAs within the device and between devices to solve tightly coupled problems. Differential lines with multi-gigabit transceivers connected to them are used as the main connections between FPGAs. It provides exchange at the velocity up to 25 Gbit/s. Information interaction between the RCD is performed through optical channels with the capacity up to 4.5 Tbit/s. Immersion technology is used for cooling components of computing system. It provides the removal of the total heat output up to 20 kW. The developed power supply configuration is based on the input constant voltage of 380 V and provides stable power supply to the components. Owning to the implementation of time-consuming algorithms for various scientific and technical problems with the high real performance, it is possible to widespread use of the Arcturus supercomputer. Scaling of computing nodes will allow designing an entire computing circuit of a supercomputer with the performance up to several tens of Petaflops.
